Steel-Alternative Windows
The Ultimate Steel Window Alternative
Alternatively Known as: Art-Deco Windows; Heritage Windows
Our Steel-Alternative Windows are engineered to be the perfect replacement for traditional steel windows. Where steel windows don’t have a thermal-break, they are prone to cold-bridging and rely heavily on incredibly over-spec’d krypton-filled glazing just to pass UK Building Regulations. Our aluminium alternatives contain a polyamide thermal-break in their design which allow for increased energy efficiency while maintaining that classic ‘Crittall-style’ sightlines.

Design

Stepped Design.
Our Steel-Alternative Windows are fabricated with a specially ‘stepped’ profile to closely mimic traditional hot-rolled steel sections.
Handles & Hardware.
Our Steel-Alternative Windows come furnished with secure, key-lockable window handles to customise the appearance to suit traditional or modern homes.
Glass & Glazing.
Our Steel-Alternative Windows are glazed with energy-efficient Insulated Glass Units (IGUs) that we hand-manufacture and argon fill at our factory in Waterlooville.
Powder Coated Finishes.
Our Steel-Alternative Windows are available in rich coloured and textured finishes using a quality powder coating process.
French Windows.
Our Steel-Alternative Windows can be specified as French Casements which have a ‘floating mullion’ so no vertical bar interrupts your view when opened.
Technology
Security & Locking.
Our Steel-Alternative Windows are manufactured with strong, multi-point locks which contain bi-directional ‘mushroom cams’.
Nightvent Facility.
Our Steel-Alternative Windows use two-stage keeps to allow the sashes to be securely locked in a slightly open position for ventilation.
Maintenance.
Our Steel-Alternative Windows are designed with easy-clean hinges; wipe-clean profiles and easy-to-lubricate mechanisms.
Sustainability.
Our Steel-Alternative Windows are made of aluminium: a material with a typical 95% recycle rate and end-of-life.
